Westpark Tollway

Houston, Texas


Westpark Tollroad Authority


Balfour Beatty Construction, Inc.


April 01, 2003

The Westpark Tollway project was designed using Slotted Drain to collect sheet flow on the roadway. Balfour Beatty Construction, Inc. was pleased at the fact that he could receive pipe within two weeks of placing the order due to the locality of our plant.

Contech Slotted Drain is a practical, aesthetically pleasing inlet for the efficient removal of surface water on streets and highways. It also is widely used in parking lots and similar locations to remove sheet flow without complex multiple grades or water channeling devices.

Slotted Drain is fabricated from Corrugated Steel Pipe, cut along a longitudinal axis. A trapezoidal or straight-sided grate with reinforcing spacer plates is welded in place to form a 1 3/4-in. -wide slot opening which collects runoff and channels it to the pipe below.

Technical Description:

  • Products Used:
  • Slotted Drain™ 5000 LF of 18-in. diameter with 2 ½-in. High Grade
